Treatments for wireworms should not be applied unless wireworms are known to be present or have caused damage in the previous season. A few insecticides (active ingredients) that may be used in home gardens for the management of wireworms include bifenthrin (3A), pyrethrins (3A), and zeta-cypermethrin (3A).
How do you treat wireworms in soil?
